How can I connect several links in the input node?
Links are created using node_tree.links.new:


  new(input, output, verify_limits=True)
  
  Add a node link to this node tree
  
  Parameters:
  
  
  input (NodeSocket, (never None)) – The input socket
  output (NodeSocket, (never None)) – The output socket
  verify_limits (boolean, (optional)) – Verify Limits, Remove existing links if connection limit is exceeded
  
  
  Returns: New node link
  
  Return type: NodeLink
